METHOD OF FEEDING SHINGLE-BOLTS T0 KNIVES.

Specification of Letters Patent No. 13,666, dated October 9, 1855.

To all whom t may concern Beit known that I, IVM. J. Soorr, of Carthage,in the county of Jeerson, in the State of New York, have invented a newand useful Improvement in the Construction and Operation of Feedwork toShingle- Cutting Machines; and I do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawings and the letters marked thereon.

The nature of my invention consistsfirstly, in the use of the twohandles (E E) attached to the cams (o e) for depressing or throwing outof gear the arm (M); secondly, in pivoting ithe arm (M) to a movable bar(L) for the purpose of more readily and accurately adjusting the saidarm (M); thirdly, in the application and peculiar construction of alever one end of which is attached to the knife frame (H) and the otherto hand (g), which operate upon the ratchet (It).

To enable others skilled in the art to make and use my invention, I willproceed to describe its construct-ion and operation.

I construct the frame of the machine in the usual way as represented atA, A, A, A, B, o, GLI, and also the knife frame (II) as generallyconstructed. I construct the carriage with the frame for holding theblock and the racks (a a) which are fed forward alternately by the cams(cl d) which are attached to each end of the shaft (D) and so adjustedthat they operate alternately upon the two racks for the purpose offeeding the carriage in such a manner that at. each stroke of the knifeits face is at t-he required angle with said knife.

(h) is the ratchet attached to shaft (D). Said ratchet is rotated bymeans of the hand (g) which is attached to one end of the lever (i),which lever (i) receives a vibratory motion from the knife frame (I-I)to which it is attached by the rod passing through the stand (o).

(r. n) are two adjustable stops against which the stand (b), (which isattached to the knife frame,) strikes alternately in its upward anddownward motion, thus give t-he vibratory motion to the lever which iscommunicated by the hand (g) to the ratchet (7i), from thence throughthe shaft to the cams (e, 1),) which operate upon the racks (a, a.) andthus feed the carriage bearing4 the block, to the knife.

(E, E) are the handled cams for throwing down the arm (M) for thepurpose of allowing the carriage to be run back to receive another blockand repeat the operation already described.

(L), (L), are two bars to which the arm (M, M,) are pivoted, said barsbeing adjustable for the purpose of more readily adjusting the arms (M,

(7c, 76,) are two springs for keeping the arms (M, M) in gear with theracks (a, a,) when the cams are thrown up.

(Z) is a spring attached to the lever (f) to throw the hand (g) over thetooth of the ratchet (7L).

That I claim as my invention 'and desire to secure by Letters Patent,is,

l. The application and construction of the two handled cams (v, o) alsothe adjustability of the arms (M, M) by means of the bars (L, L,) asdescribed.

2. I claim the combination of the rocking lever :.clutch or hand (g)lever (f) and spring (Z) with the knife frame for the purpose of feedingintermittingly the block to the knives in the manner described.
